Arcana — Privacy Policy

Last updated: 2026-10-18

What is stored on your device

• Your journal: the date, art, question, result and reading of each reading you keep.
• Birth details you enter for astrology, BaZi or numerology (date, time, place), and any people you add for compatibility.
• Your settings (deck, sound, haptics, reminder).
• A random identifier created by the app. It is not linked to you, your device's advertising identifier or any other app.

Deleting a reading removes it; deleting the app removes all of it. If you use the watch app, up to eight recent readings are copied to your own paired watch.

What is sent, and to whom

Only when you ask for an AI reading, Arcana sends the following to the Arcana reading service, which we run on Cloudflare. The service asks Google's Gemini AI model to write the reading, under Google's API terms, and sends it back. It does not store what you sent or the reading.

• Every art: your question, if you typed one, and the result drawn on your device (the cards, the hexagram, the numbers). For gematria, the word or name you weigh.
• Astrology, BaZi and numerology: facts calculated on your device from your birth details: chart positions, houses and aspects, the four pillars and your current age, or the digits of your birth date. Your birth date, time and name themselves are not sent.
• Palmistry: the photo of your palm you take for that reading, sent once and not stored. The app deletes it afterwards and never keeps it in your journal.
• Birthplace search: the place name you type is looked up through the service with the Open-Meteo geocoder. Answers are cached by place name for 30 days.

Without a connection, or when your readings for the day are used, Arcana reads on the device from its built-in traditional meanings, and nothing is sent.

Like most web services, Cloudflare keeps short-lived request logs (such as the address requested and the time), which we use only to keep the service running.

Daily readings

Each request carries the app's random identifier so the service can keep the daily allowance: one AI reading a day plus three welcome gifts and one palm reading to try, or up to 40 readings a day in the Sanctum. The service keeps, for that identifier only, a daily counter that expires after the day, and markers that the welcome gifts and the palm reading were used.

The Sanctum (purchases)

The Sanctum is sold through the App Store, Google Play or Aptoide, which handle the payment; we never see your payment details. After a purchase, and when the app starts while it is active, the app sends the store's proof of purchase (product, purchase token or signed transaction) with the random identifier to the reading service, which checks it with the store and records that the Sanctum is open on this device until it ends. That record keeps the product, a fingerprint of the purchase and the end date, and is removed a few days after the Sanctum ends.

Notifications

If you turn on the card-of-the-day reminder, it is scheduled on your device. No push service is involved.

Permissions

• Camera: only for a palm reading, when you start one.
• Notifications: only for the optional daily reminder.
• Motion: shaking the coins or the crystal ball uses your device's motion sensor, on the device only.

Arcana does not use your microphone, location, contacts or photo library.

Children

Arcana is meant for adults and is not directed at children.

For entertainment

Arcana is for entertainment and self-reflection. It does not predict the future and is no substitute for medical, legal, financial or other professional advice.
